Abstract
An evaporative cooler in which a series of evaporative pads are positioned in a spaced apart relationship. Water from a reservoir is deposited onto the pads to moisten them. As the water on the pads evaporates, the surrounding air is cooled; thereby becoming denser and settling through the outlet at the bottom of the housing and into the area to be cooled. The falling cool air draws in warm air at the top of the housing, which in turn is then cooled by the pads to continue the cycle.
Claims19
An evaporative cooler comprising:
- a) a housing having,
- 1) an exhaust opening located at the bottom of the housing,
- 2) a water reservoir, and,
- 3) air inflow openings configured to permit ambient air to enter said housing;
- b) at least two substantially circular evaporative pads positioned in spaced apart relationship to each other within said housing;
- and,
- c) a pump drawing water from said water reservoir and depositing said water onto said at least two substantially circular evaporative pads.

5 more elements
An evaporative cooler comprising:
- a) a housing having an exhaust opening located at the bottom thereof and at least one air inflow opening configured to permit ambient air to enter said housing;
- b) a reservoir containing water;
- c) at least two substantially circular evaporative pads positioned in spaced apart relationship to each other within said housing, said spaced apart at least two substantially circular evaporative pads occupying a majority of an interior space of said housing;
- and,
- d) a pump drawing water from said water reservoir and depositing said water onto said at least two substantially circular evaporative pads.
